Very high-quality ring modulator

While this pedal is far from being a one-trick pony, it definitely has it's left and right lateral limits as far as where you can go with it. As much as you can chalk it up as "just a really expensive ring mod", the quality of the pedal itself as well as the sound is amazing. I can dial in tremolo sounds or get really high-pitch laser gun noises all by just adjusting a few knobs. And the knobs are not in constant need of adjusting by hand to keep things interesting, there are dedicated inputs for foot controllers. That way with a small string of expression pedals, you can sit on a stool and take this thing for a ride. The sine and square wave switch as well as the low and high grant you the ability to completely shift the parameters of a given setting. The LFO is a a nice touch, as you can dial in just the right amount of effect from one of the signals you have dialed in. Great control over what some see as a single dimensional effect. Word of caution: like a lot of ring modulators on the market, this one "bleeds" into the bypassed signal when disengaged, so I used a home-made loop bypass pedal to take it completely out of my signal chain when not in use.

I have started to use it on bus's however to give a nice LFO modulation to things like reverbs and such when Im trying to be creative.

I don't use this as much as I wish TBH. I use it mostly in extended fx chains where I am already using on of my other mooger foogers. I hardly ever use this thing by itself.
